Definitions
- the present invention relates to a turnstile, and in particular, to a switch device of a turnstile passage.
- a barrier of a turnstile passage in the prior art is usually divided into three types: a tripod type, a sliding barrier type, and a swing barrier type.
- the tripod type in the prior art adopts a rotating manner, so that each inclining bar needs to be rotated 120 degrees each time to allow a pedestrian to pass. Therefore, it is very easy to cause a collision with a pedestrian due to a card not properly swiped.
- obstruction of the inclining bar causes great inconvenience and unnecessary trouble.
- the sliding barrier type has a complex structure and high cost, and is prone to fail to operate normally due to a circuit failure.
- a barrier of the swing barrier type in the prior art When a barrier of the swing barrier type in the prior art is opened and closed, it does not move in a translational manner but rotates in an arc around a support shaft. Further, because a support shaft or a fulcrum needs to support the weight of a flap, the support shaft requires to have a higher strength, it is necessary to use a higher-power motor to drive or to use a low-power motor in combination with of a gearbox to solve problems of a torque and a rotation speed of the support shaft or the fulcrum, as disclosed in patent publication document 201320428775.X, a transmission structure is complicated with high control accuracy requirements and high costs.
- the technical problem to be solved by the present invention is to provide a switch device of a turnstile passage, which simplifies a transmission structure and satisfies the use requirements of opening and closing control of a flap.
- the present invention provides a switch device of a turnstile passage, including a flap, a base, a frame,
- a guide rail mechanism arranged on the base and movably connected to the flap;
- connecting rod swing mechanism arranged on the frame, where one end of the connecting rod swing mechanism is rotationally connected to the flap so that the flap on the guide rail mechanism reciprocates between a closed position and an open position of the turnstile passage when the connecting rod swing mechanism swings;
- a driving mechanism rotationally connected to the other end of the connecting rod swing mechanism, and configured to drive the connecting rod swing mechanism to swing.
- the switch device of the turnstile passage of the present invention uses a combination of the driving mechanism and the connecting rod swing mechanism to indirectly drive movement of the flap.
- the flap can move stably along the guide rail mechanism during a swinging process of the connecting rod swing mechanism, and then realize opening and closing of the turnstile passage. Therefore, compared with the prior art, this application eliminates the need to turn the flap to close or open the turnstile passage, and can meet requirements of opening and closing control of the flap without adopting a support shaft and a gearbox, which simplifies a transmission structure.
- this application can reduce a friction generated by a plurality of parts of the switch device during operation, improve a movement accuracy thereof, and ensure a stable operation of the connecting rod swing mechanism, and extend a service life thereof.
- the guide rail mechanism includes a guide rail arranged on the base, and a rolling bearing arranged on the flap and in a rolling connection to the guide rail. Because the rolling bearing is rolled on the guide rail, a friction of the flap in a translation process is reduced, so that the flap can slide stably on a sliding rail, and noise generated during a sliding process is reduced.
- the connecting rod swing mechanism includes at least one swing rod rotationally connected to the frame, one end of the swing rod being rotationally connected to the flap, and the other end thereof being rotationally connected to the driving mechanism.
- the driving mechanism drives the swing rod to swing to provide a pushing force of the flap.
- this structure makes full use of a lever principle, so that the driving mechanism only needs a small thrust to push the swing rod to rotate, thereby indirectly driving the flap to translate on the sliding rail.
- the connecting rod swing mechanism further includes a synchronous connecting rod rotationally connected to each swing rod and the driving mechanism. Therefore, one force applied by the driving mechanism is transformed into a plurality of forces through the connecting rod swing mechanism, thereby making the flap more balanced when a force is applied thereto.
- each swing rod is driven to be synchronously rotated by means of the synchronous connecting rod, which is beneficial to balanced stress of the flap.
- the swing rod includes a drive swing rod rotationally connected to the synchronous connecting rod, and a driven swing rod connected to the drive swing rod.
- One end of the driven swing rod is rotationally connected to the frame via a swing rod shaft, and the other end thereof is rotationally connected to the flap via a rotating shaft.
- Each drive swing rod is rotationally connected to the synchronous connecting rod via a corresponding synchronous shaft, respectively.
- each synchronous shaft is parallel to the swing rod shaft and the rotating shaft.
- the drive swing rods are parallel to each other; and the driven swing rods are parallel to each other. Therefore, a magnitude and a direction of the transmission force can be changed through mutual interaction and length change between the drive swing rod and the driven swing rod, so that a moving path of the flap meets actual requirements when a swing amplitude of the synchronous connecting rod is relatively small. This is conducive to reducing the length of the synchronous connecting rod and power of a driving motor, which is beneficial to a space layout inside a turnstile.
- an axial direction of the synchronous connecting rod and a sliding direction of the flap on the guide rail mechanism are perpendicular to each other.
- Shaft centers between the swing rod shafts and shaft centers between the rotating shafts are all located on the same axis parallel to the synchronous connecting rod. Therefore, the connecting rod swing mechanism forms a stable parallelogram structure, which is beneficial to design and control of strokes of the synchronous connecting rod and the flap.
- the drive swing rod and the driven swing rod are perpendicular to each other. Therefore, a rigid connection between the drive swing rod and the driven swing rod is improved, and transmission efficiency is optimized.
- the flap includes a flap body, a bracket, a sliding rail arranged on the bracket, and a slider slidably arranged on the sliding rail for being rotationally connected to the connecting rod swing mechanism.
- the flap body restricts upward degree of freedom of the flap body under its own weight, and restricts downward degree of freedom of the flap body under support of the guide rail mechanism. Therefore, when the connecting rod swing mechanism swings, a translational thrust is generated on the flap, and a phenomenon of jamming at one end of a rotatable connection between the connecting rod swing mechanism and the flap is avoided when the flap slides on the guide rail mechanism.
- the sliding rail is a linear sliding rail
- the sliding direction of the slider is perpendicular to a sliding direction of the flap on the guide rail mechanism. Therefore, when the slider is driven by the connecting rod swing mechanism to swing leftwards and rightwards, a relative linear movement is generated between the linear sliding rail and the slider, so that a thrust generated by the connecting rod swing mechanism is transformed to be a translational thrust parallel to a sliding direction of the flap to the maximum extent.
- the connecting rod swing mechanism includes an adjusting rod parallel to an axial direction of the linear sliding rail and connected to each slider for adjusting a distance between the sliders. Therefore, synchronization of each slider is maintained when the slider is moved, while rotation movement of the flap is eliminated to the maximum extent when the flap is moved, thereby avoiding a phenomenon of inclination of the flap due to uneven stress when the flap is moved.
- the driving mechanism includes a revolving arm rotationally connected to the connecting rod swing mechanism at one end thereof, a rotating arm rotationally connected to the revolving arm, and a driving shaft of a driving motor rotationally connected to the rotating arm; where the rotating arm is driven by the driving shaft to perform a circular motion.
- rotation motion of the driving motor is transformed into circular motion of the revolving arm, enabling the rotating arm to swing regularly, so that the flap performs regular translation in conjunction with the guide rail mechanism, which improves control precision.
- the driving mechanism further includes an opening limiter and a closing limiter that are arranged on the frame; where the flap is in an open position when the flap stops rotating because the rotating arm touches the opening limiter.
- the flap is in a closed position when the flap stops because the rotating arm touches the closing limiter. Therefore, through interaction of the opening limiter and the closing limiter, a swing angle of the rotating arm is limited, thereby limiting a swing amplitude of the swing arm, then controlling a swing amplitude of the connecting rod swing mechanism, and further controlling a movement stroke and a movement range of the flap.
- the driving mechanism further includes a protective cover fixedly connected to the frame, an electromagnetic brake assembly arranged in the protective cover and connected to the driving shaft, and a controller electrically connected to the electromagnetic brake assembly and the driving motor.
- the driving mechanism further includes a resetting mechanism arranged on the frame and connected to the connecting rod swing mechanism.
- the driving mechanism or the flap is used for enabling an automatic return of the connecting rod swing mechanism to the open position from the closed position. Therefore, when the turnstile loses power or encounters a power failure, the flap automatically resets to an open state from a closed state to ensure smooth passage of the turnstile passage and avoid a crowded and blocked passenger flow.
- the resetting mechanism includes a first tension spring seat arranged on the revolving arm of the driving mechanism, a second tension spring seat arranged on the frame, and a tension spring both ends of which are connected to the first tension spring seat and the second tension spring seat, respectively; where the tension spring is in a stretched state when the flap is in the closed position.
- the tension spring is in a stretched state when the flap is in the closed position.

Abstract
Description
- The present invention relates to a turnstile, and in particular, to a switch device of a turnstile passage.
- At present, a barrier of a turnstile passage in the prior art is usually divided into three types: a tripod type, a sliding barrier type, and a swing barrier type.
- However, the tripod type in the prior art adopts a rotating manner, so that each inclining bar needs to be rotated 120 degrees each time to allow a pedestrian to pass. Therefore, it is very easy to cause a collision with a pedestrian due to a card not properly swiped. In addition, when a pedestrian takes a luggage and other items to pass or an overweight pedestrian passes, obstruction of the inclining bar causes great inconvenience and unnecessary trouble. However, the sliding barrier type has a complex structure and high cost, and is prone to fail to operate normally due to a circuit failure.
- When a barrier of the swing barrier type in the prior art is opened and closed, it does not move in a translational manner but rotates in an arc around a support shaft. Further, because a support shaft or a fulcrum needs to support the weight of a flap, the support shaft requires to have a higher strength, it is necessary to use a higher-power motor to drive or to use a low-power motor in combination with of a gearbox to solve problems of a torque and a rotation speed of the support shaft or the fulcrum, as disclosed in patent publication document 201320428775.X, a transmission structure is complicated with high control accuracy requirements and high costs.
- In view of the forgoing-mentioned shortcomings or deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a switch device of a turnstile passage, which simplifies a transmission structure and satisfies the use requirements of opening and closing control of a flap.
- In order to solve the forgoing technical problems, the present invention provides a switch device of a turnstile passage, including a flap, a base, a frame,
- a guide rail mechanism arranged on the base and movably connected to the flap;
- a connecting rod swing mechanism arranged on the frame, where one end of the connecting rod swing mechanism is rotationally connected to the flap so that the flap on the guide rail mechanism reciprocates between a closed position and an open position of the turnstile passage when the connecting rod swing mechanism swings; and
- a driving mechanism rotationally connected to the other end of the connecting rod swing mechanism, and configured to drive the connecting rod swing mechanism to swing.
- Compared with the prior art, the switch device of the turnstile passage of the present invention uses a combination of the driving mechanism and the connecting rod swing mechanism to indirectly drive movement of the flap. In addition, by means of movable connection between the flap and the guide rail mechanism and support by the guide rail mechanism arranged on the base, the flap can move stably along the guide rail mechanism during a swinging process of the connecting rod swing mechanism, and then realize opening and closing of the turnstile passage. Therefore, compared with the prior art, this application eliminates the need to turn the flap to close or open the turnstile passage, and can meet requirements of opening and closing control of the flap without adopting a support shaft and a gearbox, which simplifies a transmission structure. In addition, because the connecting rod swing mechanism is rotationally connected to the driving mechanism and the flap, this application can reduce a friction generated by a plurality of parts of the switch device during operation, improve a movement accuracy thereof, and ensure a stable operation of the connecting rod swing mechanism, and extend a service life thereof.
- Further, preferably, the guide rail mechanism includes a guide rail arranged on the base, and a rolling bearing arranged on the flap and in a rolling connection to the guide rail. Because the rolling bearing is rolled on the guide rail, a friction of the flap in a translation process is reduced, so that the flap can slide stably on a sliding rail, and noise generated during a sliding process is reduced.
- Further, preferably, the connecting rod swing mechanism includes at least one swing rod rotationally connected to the frame, one end of the swing rod being rotationally connected to the flap, and the other end thereof being rotationally connected to the driving mechanism. The driving mechanism drives the swing rod to swing to provide a pushing force of the flap. In addition, this structure makes full use of a lever principle, so that the driving mechanism only needs a small thrust to push the swing rod to rotate, thereby indirectly driving the flap to translate on the sliding rail.
- Further, preferably, there are at least two swing rods, and the connecting rod swing mechanism further includes a synchronous connecting rod rotationally connected to each swing rod and the driving mechanism. Therefore, one force applied by the driving mechanism is transformed into a plurality of forces through the connecting rod swing mechanism, thereby making the flap more balanced when a force is applied thereto. In addition, each swing rod is driven to be synchronously rotated by means of the synchronous connecting rod, which is beneficial to balanced stress of the flap.
- Further, preferably, the swing rod includes a drive swing rod rotationally connected to the synchronous connecting rod, and a driven swing rod connected to the drive swing rod. One end of the driven swing rod is rotationally connected to the frame via a swing rod shaft, and the other end thereof is rotationally connected to the flap via a rotating shaft. Each drive swing rod is rotationally connected to the synchronous connecting rod via a corresponding synchronous shaft, respectively.
- Further, preferably, each synchronous shaft is parallel to the swing rod shaft and the rotating shaft. The drive swing rods are parallel to each other; and the driven swing rods are parallel to each other. Therefore, a magnitude and a direction of the transmission force can be changed through mutual interaction and length change between the drive swing rod and the driven swing rod, so that a moving path of the flap meets actual requirements when a swing amplitude of the synchronous connecting rod is relatively small. This is conducive to reducing the length of the synchronous connecting rod and power of a driving motor, which is beneficial to a space layout inside a turnstile.
- Further, preferably, an axial direction of the synchronous connecting rod and a sliding direction of the flap on the guide rail mechanism are perpendicular to each other. Shaft centers between the swing rod shafts and shaft centers between the rotating shafts are all located on the same axis parallel to the synchronous connecting rod. Therefore, the connecting rod swing mechanism forms a stable parallelogram structure, which is beneficial to design and control of strokes of the synchronous connecting rod and the flap.
- Further, preferably, the drive swing rod and the driven swing rod are perpendicular to each other. Therefore, a rigid connection between the drive swing rod and the driven swing rod is improved, and transmission efficiency is optimized.
- Further, preferably, the flap includes a flap body, a bracket, a sliding rail arranged on the bracket, and a slider slidably arranged on the sliding rail for being rotationally connected to the connecting rod swing mechanism. Through relative movement between the slider and the flap body, the flap body restricts upward degree of freedom of the flap body under its own weight, and restricts downward degree of freedom of the flap body under support of the guide rail mechanism. Therefore, when the connecting rod swing mechanism swings, a translational thrust is generated on the flap, and a phenomenon of jamming at one end of a rotatable connection between the connecting rod swing mechanism and the flap is avoided when the flap slides on the guide rail mechanism.
- Further, preferably, the sliding rail is a linear sliding rail, and the sliding direction of the slider is perpendicular to a sliding direction of the flap on the guide rail mechanism. Therefore, when the slider is driven by the connecting rod swing mechanism to swing leftwards and rightwards, a relative linear movement is generated between the linear sliding rail and the slider, so that a thrust generated by the connecting rod swing mechanism is transformed to be a translational thrust parallel to a sliding direction of the flap to the maximum extent.
- Further, preferably, there are at least two sliders. The connecting rod swing mechanism includes an adjusting rod parallel to an axial direction of the linear sliding rail and connected to each slider for adjusting a distance between the sliders. Therefore, synchronization of each slider is maintained when the slider is moved, while rotation movement of the flap is eliminated to the maximum extent when the flap is moved, thereby avoiding a phenomenon of inclination of the flap due to uneven stress when the flap is moved.
- Further, preferably, the driving mechanism includes a revolving arm rotationally connected to the connecting rod swing mechanism at one end thereof, a rotating arm rotationally connected to the revolving arm, and a driving shaft of a driving motor rotationally connected to the rotating arm; where the rotating arm is driven by the driving shaft to perform a circular motion. With this structure, rotation motion of the driving motor is transformed into circular motion of the revolving arm, enabling the rotating arm to swing regularly, so that the flap performs regular translation in conjunction with the guide rail mechanism, which improves control precision.
- Further, preferably, the driving mechanism further includes an opening limiter and a closing limiter that are arranged on the frame; where the flap is in an open position when the flap stops rotating because the rotating arm touches the opening limiter. The flap is in a closed position when the flap stops because the rotating arm touches the closing limiter. Therefore, through interaction of the opening limiter and the closing limiter, a swing angle of the rotating arm is limited, thereby limiting a swing amplitude of the swing arm, then controlling a swing amplitude of the connecting rod swing mechanism, and further controlling a movement stroke and a movement range of the flap.
- Further, preferably, in order to intelligently control a flap opening speed, a flap closing speed and strength, the driving mechanism further includes a protective cover fixedly connected to the frame, an electromagnetic brake assembly arranged in the protective cover and connected to the driving shaft, and a controller electrically connected to the electromagnetic brake assembly and the driving motor.
- Further, preferably, the driving mechanism further includes a resetting mechanism arranged on the frame and connected to the connecting rod swing mechanism. The driving mechanism or the flap and is used for enabling an automatic return of the connecting rod swing mechanism to the open position from the closed position. Therefore, when the turnstile loses power or encounters a power failure, the flap automatically resets to an open state from a closed state to ensure smooth passage of the turnstile passage and avoid a crowded and blocked passenger flow.
- Further, preferably, the resetting mechanism includes a first tension spring seat arranged on the revolving arm of the driving mechanism, a second tension spring seat arranged on the frame, and a tension spring both ends of which are connected to the first tension spring seat and the second tension spring seat, respectively; where the tension spring is in a stretched state when the flap is in the closed position. Through an elastic return action of the tension spring, the synchronous connecting rod can be pulled so that the connecting rod swing mechanism instantly returns to an initial position, that is, the flap quickly moves to the open position, which saves power and improves resetting efficiency.

- As shown in
FIGS. 1 and 2 ,Embodiment 1 of the present invention provides a switch device of a turnstile passage, consisting of aflap 1, abase 2, aframe 3, a guide rail mechanism 4 arranged on thebase 2 and movably connected to the flap, a connectingrod swing mechanism 5 arranged on theframe 3, and a driving mechanism 6. - One end of the connecting
rod swing mechanism 5 is rotationally connected to theflap 1 so that theflap 1 reciprocates between a closed position and an open position of the turnstile passage on the guide rail mechanism 4 when the connectingrod swing mechanism 5 swings. Normally, the base is arranged inside a turnstile. As shown inFIG. 1 , when theflap 1 moves to the open position, the most part of the flap is located outside the turnstile. As shown inFIG. 2 , when theflap 1 moves to the closed position, theflap 1 is for the most part or completely inside the turnstile. - The driving mechanism 6 is rotationally connected to the other end of the connecting
rod swing mechanism 5 for driving the connectingrod swing mechanism 5 to swing. - It can be seen from the forgoing content that the switch device of the turnstile passage adopts a combination of the driving mechanism 6 and the connecting
rod swing mechanism 5 to indirectly drive theflap 1 to move. In addition, by means of movable connection between theflap 1 and the guide rail mechanism 4 and support by the guide rail mechanism arranged on the base, theflap 1 can move stably along the guide rail mechanism 4 during a swinging process of the connectingrod swing mechanism 5, thereby realizing opening and closing of the turnstile passage. Therefore, compared with the prior art, this application eliminates the need to turn theflap 1 to close or open the turnstile passage, and can meet use requirements of opening and closing control of the flap without using structures such as a support shaft and a gearbox to drive theflap 1, which simplifies a transmission structure. In addition, because the connectingrod swing mechanism 5 is rotationally connected to the driving mechanism 6 and theflap 1, a friction generated by various parts of the switch device during operation can be reduced, and movement accuracy can be improved; further, stable operation of the connectingrod swing mechanism 5 can be ensured, which extends a service life thereof. - Specifically, as shown in
FIG. 1 , the guide rail mechanism 4 in this embodiment mainly consists of aguide rail 41 arranged on thebase 2 and a rollingbearing 42 arranged on theflap 1 and in rolling connection with theguide rail 41. Therefore, the rollingbearing 42 rolls on theguide rail 41, which can reduce a friction of theflap 1 during a translation process of theflap 1 so that theflap 1 can move stably on theguide rail 41, thereby reducing noise generated during movement. As shown inFIG. 5 , the rollingbearing 42 in this embodiment is fixed on theflap 1 via asupport seat 43, and the other end is supported by theguide rail 41. Therefore, the rolling bearing is resistant to bending and deformation during use, so there is no need to use a material with high specifications, which reduces production and manufacturing costs. In addition, the rollingbearing 42 in this embodiment can be a sliding bearing sleeved on thesupport base 43 or a pulley arranged on thesupport base 43, which is not specifically limited and described in this embodiment. - In this embodiment, as a preference, the
guide rail 41 is made of a high-hardness polyurethane material. In addition, it should be understood that the guide rail mechanism 4 in this embodiment can also consist of a slider arranged at the bottom of theflap body 11 and slidably fitted with theguide rail 41 to realize movement of theflap 1 on theguide rail 41. Therefore, how theguide rail 41 and theflap 1 form a movable connection is not specifically limited and elaborated in this embodiment. Moreover, as a further preference, a length direction and a horizontal direction of theguide rail 41 in this embodiment are parallel to each other, so that theflap 1 can reciprocate on theguide rail 41 in a horizontal direction. - As shown in
FIGS. 2 and 4 , the connectingrod swing mechanism 5 in this embodiment can consist of at least oneswing rod 51 rotationally connected to theframe 3. One end of theswing rod 51 is rotationally connected to theflap 1, and the other end thereof is rotationally connected to the driving mechanism 6. Therefore, the driving mechanism 6 drives theswing rod 51 to swing to provide a driving force of theflap 1. In addition, this structure makes full use of a lever principle, so that the driving mechanism 6 can push theswing rod 51 to rotate with only a small thrust, thereby indirectly driving theflap 1 to translate on the slidingrail 13. - In details, as a preference, only two
swing rods 51 are described as examples in this embodiment, and the connectingrod swing mechanism 5 further includes a synchronous connectingrod 52 rotationally connected to eachswing rod 51 and the driving mechanism 6. As a result, one force applied by the driving mechanism 6 is transformed into a plurality of forces through the connectingrod swing mechanism 5 so that theflap 1 is more balanced when a force is applied to theflap 1. In addition, eachswing rod 51 is driven to be synchronously rotated by means of the synchronous connectingrod 52, which is beneficial to balanced stress of theflap 1 so that theflap 1 slides stably on the guide rail mechanism 4. It should be understood for the person skilled in the art that a plurality ofswing rods 51 in this embodiment can also be designed according to an actual situation, so as to realize transformation from one force to a plurality of forces, which is beneficial to balanced stress of the flap. This is not elaborated herein. - Further, as a preference, as shown in
FIGS. 2 and 3 , theswing rod 51 in this embodiment mainly consists of adrive swing rod 511 rotationally connected to the synchronous connectingrod 52 and a drivenswing rod 512 connected to thedrive swing rod 511. One end of the drivenswing rod 512 is rotationally connected to theframe 3 through aswing rod shaft 53, and the other end thereof is rotationally connected to theflap 1 through a rotating shaft (not shown in the drawings). Eachdrive swing rod 511 is rotationally connected to the synchronous connectingrod 52 through the correspondingsynchronous shaft 55, respectively. Therefore, a magnitude and a direction of the transmission force can be changed through mutual interaction and length change between thedrive swing rod 511 and the drivenswing rod 512, so that a moving path of theflap 1 meets actual requirements when a swing amplitude of the synchronous connectingrod 52 is relatively small. This is conducive to reducing the length of the synchronous connectingrod 52 and power of a drivingmotor 61, which is beneficial to a space layout inside a turnstile. - Further, as preference, as shown in
FIG. 3 , in this embodiment, eachsynchronous shaft 55 is parallel to theswing rod shaft 53 and the rotating shaft. Thedrive swing rods 511 are parallel to each other; and the drivenswing rods 512 are parallel to each other. Through this arrangement, rotation of the drivenswing rod 512 and theactive swing rod 511 can be kept synchronized during a swing process of the synchronous connectingrod 52, so as to avoid a phenomenon of inclination caused by upper and lower uneven forces on theflap 1 during a sliding process of theflap 1. - Further, as a preference, as shown in
FIGS. 3 and 4 , in this embodiment, an axial direction of the synchronous connectingrod 52 and a sliding direction of theflap 1 on the guide rail mechanism 4 are perpendicular to each other. Shaft centers between theswing rod shafts 53 and shaft centers between the rotating shafts are all located on the same axis parallel to the synchronous connectingrod 52. Therefore, the connectingrod swing mechanism 5 forms a stable parallelogram structure, which is beneficial to design and control of strokes of the synchronous connectingrod 52 and theflap 1. - Further, as a preference, the
drive swing rod 511 and the drivenswing rod 512 are perpendicular to each other in this embodiment, so as to improve a rigid connection between thedrive swing rod 511 and the drivenswing rod 512 and optimize transmission efficiency. - In addition, it should be noted that a length of the
drive swing rod 511 in this embodiment is less than a length of the drivenswing rod 512, and a position where thedrive swing rod 511 is rotationally connected to the synchronous connectingrod 52 through thesynchronous shaft 55 is lower than a position where thedrive swing rod 51 is rotationally connected to theframe 3, which is beneficial to a layout of the connectingrod swing mechanism 5 inside the turnstile. - As shown in
FIG. 4 , the base in this embodiment is provided with a swingrod shaft hole 19 for inserting one end of thecorresponding swing shaft 53 and forming a rotatable connection through a correspondingbearing sleeve 531. One end of theswing shaft 53 is also inserted into a through hole (marked in the drawings) of the drivenswing rod 512 to form a rotatable connection through the correspondingbearing sleeve 531. In the same way, two ends of the rotating shaft adopt the corresponding bearing sleeve to form a rotatable connection with theflap 1 and the drivenswing rod 512, respectively. Here, it should be noted that theswing rod shaft 53 and the rotating shaft in this embodiment can be rotationally connected through a pivot connection and the like, in addition to through the bearing sleeve. In the same way, thesynchronous shaft 55 can also interact with the corresponding bearing sleeve to realize a rotatable connection between thedrive swing rod 512 and the synchronous connectingrod 52, and a rotatable connection between the revolvingarm 63 and the synchronous connectingrod 52. This embodiment does not specifically limit and describe this herein. - As shown in
FIGS. 1 to 3 , the forgoing driving mechanism 6 further includes the revolvingarm 63 rotationally connected to the connectingrod swing mechanism 5 at one end thereof, arotating arm 64 rotationally connected to the revolvingarm 63 through a connectingshaft 65, and a drivingshaft 62 of the driving motor 61 a rotationally connected to therotating arm 64. Therotating arm 64 is driven by the drivingshaft 62 to perform a circular motion. With this structure, a rotation motion of the drivingmotor 61 is transformed into a circular motion of therotating arm 64, and therotating arm 63 is facilitated to swing regularly so that theflap 1 is regularly translated under influence the influence of the interaction with the guide rail mechanism 4, which improves control accuracy. - It should be noted that in this embodiment, as a preference, the
swing arm 63 and the synchronous connectingrod 52 in this embodiment are hinged by aconnection shaft 66. Obviously, the revolvingarm 63 in this embodiment can also be directly hinged with theswing rod 51 according to actual needs, without using the synchronous connectingrod 52. Therefore, whether theswing arm 63 is hinged with the synchronous connectingrod 52 or directly connected to theswing rod 51 is not limited and elaborated in details in this embodiment. - In order to briefly explain the working principle of the switch device of this embodiment, the switch device of this embodiment consists of two symmetrically arranged
flaps 1, thebase 2, theframe 3, the guide rail mechanism 4 arranged on thebase 2 and movably connected to theflap 1, the connectingrod swing mechanism 5 arranged on theframe 3, and the driving mechanism 6, where the twobases 2 and theframe 3 are located in a housing (not marked in the drawings) of the turnstile, respectively, and the turnstile passage part is formed between the two housings. - As shown in
FIG. 1 , the twoflaps 1 move towards each other and gradually move closer to each other while sliding from an open position to a closed position along theguide rail 41 in a horizontal direction under a swing action of the corresponding connectingrod swing mechanism 5, so that the turnstile passage is closed when reaching the closed position. As shown inFIG. 2 , when the twoflaps 1 slide along theguide rail 41 from the closed position to the open position under the swing action of the corresponding connectingrod swing mechanism 5, the two flaps move backwards from each other and gradually separate from each other, thereby achieving opening of the turnstile passage. -
Embodiment 2 of the present invention provides a switch device of a turnstile passage. This embodiment is a further improvement of the forgoingEmbodiment 1. The improvement lies in: as shown inFIGS. 6 to 7 , aflap 1 in this embodiment mainly consists of aflap body 11, abracket 12, a slidingrail 13 arranged on thebracket 12, and aslider 14 slidably arranged on the slidingrail 13 for being rotationally connected to a connectingrod swing mechanism 5. Through relative movement between theslider 14 and theflap body 11, theflap body 11 restricts upward degree of freedom of the flap body under its own weight, and restricts downward degree of freedom of the flap body under support of a guide rail mechanism 4. Therefore, when the connectingrod swing mechanism 5 swings, a translational thrust is generated on theflap 1, and a phenomenon of jamming at one end of a rotatable connection between the connectingrod swing mechanism 5 and theflap 1 is avoided when theflap 1 moves on the guide rail mechanism 4. - As a preference, as shown in
FIG. 5 , the slidingrail 13 in this embodiment is a linear sliding rail, and a sliding direction of theslider 14 is perpendicular to a sliding direction of theflap 1 on the guide rail mechanism 4. Therefore, when theslider 14 is driven by the connectingrod swing mechanism 5 to swing leftwards and rightwards, a relative linear movement is generated between the linear sliding rail and theslider 14, so that a thrust generated by the connectingrod swing mechanism 5 is transformed to be a translational thrust parallel to a sliding direction of theflap 1 to the maximum extent. - It should be noted that the sliding
rail 13 in this embodiment can also be designed in an arc shape or other regular or irregular shapes according to actual conditions. This embodiment only uses the slidingrail 13 as a linear sliding rail for brief description. - As shown in
FIG. 6 , there are preferably twosliders 14 in this embodiment, which are rotationally connected to the correspondingswing rod shaft 53 in the connectingrod swing mechanism 5, respectively. It should be understood that other numbers ofsliders 14 can also be selected in this embodiment according to actual needs, and no specific limitation and description are made herein. - In addition, the
flap 1 in this embodiment further includes an adjustingrod 15 parallel to an axial direction of the linear sliding rail and connected to thesliders 14 for adjusting a distance between thesliders 14 to ensure synchronism of thesliders 14 when thesliders 14 move to the maximum extent, and to avoid a phenomenon that theflap 1 is inclined due to uneven stress during movement while eliminating rotation movement of theflap 1 when theflap 1 moves. - In details, as shown in
FIG. 6 , theflap 1 further includes a sliderdistance adjusting cap 16 arranged on theslider 14 for adjusting a length of the adjustingrod 15 to facilitate the user's adjustment and assembly. As a preference, a length of the adjustingrod 15 in this embodiment is equal to a distance between theswing rod shafts 53 ofswing rods 51 that are connected correspondingly. In conjunction with the connectingrod swing mechanism 5, a parallelogram structure is formed to ensure that a sliding direction and a sliding distance of eachslider 14 are consistent. - In addition, it should be noted that the forgoing adjusting
rod 15 can be detachably connected to theslider 14, or can be connected as a whole according to actual needs. In addition, there is one adjustingrod 15 in this embodiment. In actual application, the number of adjustingrods 15 can be correspondingly set to two, three, and so on according to the actual number of thesliders 14. Therefore, this embodiment does not specifically limit and elaborate this. - In addition, more preferably, the forgoing
slider 14 is preferably a self-lubricating silent slider, so as to eliminate noise generated when theslider 14 and the slidingrail 13 move, as much as possible. Theflap body 11 adopts a tempered glass flap, and thebracket 12 consists of a flappanel fixing frame 121 and a slidingrail fixing seat 122 arranged on the flappanel fixing frame 121. - As shown in
FIGS. 6 and 7 , theslider 14 in this embodiment consists of aslider body 141 slidably arranged on the slidingrail 13 and aslider fixing seat 142 arranged on theslider body 141 to facilitate installation of therotating shaft 54. -
Embodiment 3 of the present invention provides a switch device of a turnstile passage. This embodiment is a further improvement of any one of the forgoing embodiments. The improvement lies in: as shown inFIGS. 8 to 10 , a driving mechanism 6 in this embodiment also includes anopening limiter 8 and a closing limiter 9 that are arranged on aframe 3. Aflap 1 is in an open position when arotating arm 64 touches theopening limiter 8 and stops rotating. Theflap 1 is in a closed position when therotating arm 64 touches the closing limiter 9 and stops rotating. Therefore, through interaction of theopening limiter 8 and the closing limiter 9, a swing angle of the rotating arm is limited, thereby limiting a swing amplitude of aswing arm 63, then controlling a swing amplitude of a connecting rod swing mechanism, and further controlling a movement stroke and a movement range of theflap 1. - In addition, as shown in
FIGS. 8 and 9 , in order to intelligently control a flap opening speed, a flap closing speed and strength of theflap 1, the driving mechanism 6 further includes aprotective cover 10 fixedly connected to theframe 3, anelectromagnetic brake 20 assembly arranged in theprotective cover 10 and connected to the drivingshaft 62, and a controller electrically connected to theelectromagnetic brake 20 assembly and a drivingmotor 61. - As shown in
FIGS. 8 and 10 , theelectromagnetic brake 20 assembly in this embodiment can consist of anelectromagnetic brake 20, theprotective cover 10, and a brake shaft. Theelectromagnetic brake 20 is mounted in theprotective cover 10. One end of theprotective cover 10 is connected and fixed to the drivingmotor 61, and the other end thereof is connected and fixed to theframe 3. A stator of theelectromagnetic brake 20 is fixed in theprotective cover 10. The brake shaft is also arranged in theprotective cover 10. One end of the brake shaft is fixed on an output shaft of the drivingmotor 61, and the other end thereof is connected and fixed to a motor output connecting rod. A rotor of theelectromagnetic brake 20 is mounted on the brake shaft. A contact surface gap between the stator and the rotor is adjusted according to requirements of a manufacturer. In this case, after the stator of theelectromagnetic brake 20 is powered on, the rotor is attracted by the stator to have a certain adsorption force as a whole, and the rotor is forced to stop moving; therefore, the driving mechanism 6 is stopped, that is, theflap 1 is forced to stop moving. - In order to better explain a switching process of the switch device in this embodiment, a working principle is briefly described as follows:
- Step 1: after a barrier switch device of the turnstile passage is powered on and started, a control system is first self-checked and initialized;
- Step 2: when the driving
motor 61 is driven because the controller is triggered and sends a corresponding flap closing instruction, and when the rotating arm follows the drivingshaft 62 of the motor to rotate counterclockwise until the rotating arm is blocked by the closing limiter 9, the drivingmotor 61 stops moving when encountering resistance. At this time, theflap 1 is located in a closed position. When the drivingmotor 61 is driven because the controller is triggered and sends a corresponding flap opening instruction, and when therotating arm 64 follows the drivingshaft 62 of the motor to rotate clockwise until the rotating arm is blocked by theopening limiter 8, the drivingmotor 61 stops moving when encountering the resistance. At this time, theflap 1 is located at the open position. - In addition, it should be noted that in this embodiment, when the
flap 1 in translational movement is stressed by a forward resistance, this resistance is transmitted by the connectingrod swing mechanism 5 to the drivingmotor 61, so that the controller sends a control instruction to theelectromagnetic brake 20 after receiving a feedback signal on the drivingmotor 61. Therefore, the stator is powered on so that a magnetic adoption generated by the stator after the rotor is powered on further enables theflap 1 in a translational movement to be braked and stopped temporarily at an original place. Therefore, theflap 1 does not pinch and hit a pedestrian again when encountering the resistance, thereby preventing possibility of hurting the pedestrian. - In addition, when the
flap 1 in the closed position is slightly moved under an action of a strong external force, the controller can detect reversal of the drivingshaft 62 of the drivingmotor 61 and send a corresponding signal instruction to theelectromagnetic brake 20 so that the rotor and the stator are attracted to prevent theflap 1 from being forcibly opened. In addition, through setting of an adsorption force between the rotor and the stator, theflap 1 can also be forced to open when an externally applied force is greater than a preset opening force, so as to avoid a phenomenon that the turnstile cannot be opened due to a malfunction. In addition, through setting of control program of the controller, a slidingflap 1 can resume control after being forcibly opened, and theflap 1 can be automatically closed again under drive of the drivingmotor 61. - In addition, it is worth mentioning that as a preference, the
opening limiter 8 and the closing limiter 9 in this embodiment can be proximity switches that are communicatively connected to the controller so that after the proximity switches are triggered, the proximity switches send a trigger signal to the controller. - Therefore, the driving
motor 61 stops running to realize precise control of a stroke of theflap 1. - Embodiment 4 of the present invention provides a switch device of a turnstile passage. As shown in
FIGS. 11 to 13 , the switch device mainly consists of aflap 1, abase 2, aframe 3, abase 2, a guide rail mechanism 4 arranged on thebase 2 and movably connected to theflap 1, a connectingrod swing mechanism 5 arranged on theframe 3, a driving mechanism 6, and aresetting mechanism 7. - One end of the connecting
rod swing mechanism 5 is rotationally connected to theflap 1 so that theflap 1 reciprocates between a closed position and an open position of the turnstile passage on the guide rail mechanism 4 when the connectingrod swing mechanism 5 swings. Normally, the base is arranged inside a turnstile. As shown inFIG. 9 , when theflap 1 moves to the open position, the flap is for the most part located outside the turnstile. As shown inFIG. 10 , when theflap 1 moves to the closed position, theflap 1 is for the most part or completely inside the turnstile. - The driving mechanism 6 is rotationally connected to the other end of the connecting
rod swing mechanism 5 for driving the connectingrod swing mechanism 5 to swing. - The
resetting mechanism 7 is arranged on theframe 3 and connected to the driving mechanism 6 so that the connectingrod swing mechanism 5 automatically returns to the open position from the closed position. - It can be seen from the forgoing content that the switch device of the turnstile passage adopts a combination of the driving mechanism 6 and the connecting
rod swing mechanism 5 to indirectly drive theflap 1 to move. In addition, by means of movable connection between theflap 1 and the guide rail mechanism 4 and support by the guide rail mechanism 4 arranged on thebase 2, theflap 1 can move stably along the guide rail mechanism 4 during a swinging process of the connectingrod swing mechanism 5, thereby realizing opening and closing of the turnstile passage. Therefore, compared with the prior art, this application eliminates the need to turn theflap 1 to close or open the turnstile passage, and can meet use requirements of opening and closing control of the flap without using structures such as a support shaft and a gearbox, which simplifies a transmission structure. In addition, because the connectingrod swing mechanism 5 is rotationally connected to the driving mechanism 6 and theflap 1, a friction generated by various parts of the switch device during operation can be reduced, and movement accuracy can be improved; further, stable operation of the connectingrod swing mechanism 5 can be ensured, which extends a service life thereof. - In addition, through connection between the
resetting mechanism 7 and the driving mechanism 6, when the turnstile loses power or encounters a power failure, theflap 1 automatically resets to a open state from a closed state to ensure smooth passage of the turnstile passage and avoid a phenomenon of a crowded passenger flow. - Specifically, the
resetting mechanism 7 in this embodiment mainly consists of a firsttension spring seat 71 arranged on arotating arm 64, a second tension spring seat 72 arranged on theframe 3, and atension spring 73 both ends of which are connected to the first tension spring seat and the second tension spring seat 72, respectively. Thetension spring 73 is in a stretched state when theflap 1 is located in the closed position. - It can be seen that when the driving mechanism 6 and an electromagnetic brake assembly have failures such as power failure, a synchronous connecting
rod 52 can be pulled through an elastic recovery action of thetension spring 73 so that the connectingrod swing mechanism 5 can instantly return to an initial position, that is, theflap 1 quickly moves to the open position, which saves power and improves resetting efficiency. - In details, as shown in
FIGS. 11 to 14 , the firsttension spring seat 71 in this embodiment is a fixing block arranged on a revolvingarm 63. One end of thetension spring 73 is sleeved on a fixingbolt 74 on the fixing block, and the other end thereof is sleeved on a fixingbolt 75 arranged on thebase 2. - In addition, it should be understood for the person skilled in the art that the
tension spring 73 in theresetting mechanism 7 in this embodiment is used to connect one end of the revolvingarm 63, and can also be directly connected to the synchronous connectingrod 52 in the connectingrod swing mechanism 5 and theflap 1 to achieve the forgoing objective. Therefore, this embodiment only takes thetension spring 73 connected to the revolvingarm 63 as an example for preferred description. - In addition, as shown in
FIG. 14 , it should be understood that the guide rail mechanism 4 in this embodiment can be selected to consist of aguide rail 41 arranged on thebase 2 and a rolling bearing arranged on theflap 1 and in a rolling connection to theguide rail 41 according to actual needs. Therefore, the rollingbearing 42 rolls on theguide rail 41 so that theflap 1 can move stably on theguide rail 41 and reduce noise generated in a movement process while reducing a friction of theflap 1 during a translation process. The supported rollingbearing 42 in this embodiment is fixed on theflap 1 via asupport seat 43, and the other end is supported by theguide rail 41. Therefore, the rolling bearing is resistant to bending and deformation during use, so there is no need to use a material with high specifications, which reduces production and manufacturing costs. In addition, the supported rollingbearing 42 in this embodiment can be a sliding bearing sleeved on thesupport base 43 or a pulley arranged on thesupport base 43, which is not specifically limited and described in this embodiment. - In this embodiment, as a preference, the
guide rail 41 is made of a high-hardness polyurethane material. In addition, it should be understood that the guide rail mechanism 4 in this embodiment can also consist of a slider arranged at the bottom of theflap body 11 and slidably fitted with theguide rail 41 to realize movement of theflap 1 on theguide rail 41. Therefore, how theguide rail 41 and theflap 1 form a movable connection is not specifically limited and elaborated in this embodiment. Moreover, as a further preference, a length direction and a horizontal direction of theguide rail 41 in this embodiment are parallel to each other, so that theflap 1 can reciprocate on theguide rail 41 in a horizontal direction. - As shown in
FIGS. 11 and 14 , the connectingrod swing mechanism 5 in this embodiment can consist of at least oneswing rod 51 rotationally connected to theframe 3. One end of theswing rod 51 is rotationally connected to theflap 1, and the other end thereof is rotationally connected to the driving mechanism 6. Therefore, the driving mechanism 6 drives theswing rod 51 to swing to provide a driving force of theflap 1. In addition, this structure makes full use of a lever principle, so that the driving mechanism 6 can push theswing rod 51 to rotate with only a small thrust, thereby indirectly driving theflap 1 to translate on the slidingrail 13. - In details, as a preference, only two
swing rods 51 in this embodiment are described as examples, and the connectingrod swing mechanism 5 further includes a synchronous connectingrod 52 rotationally connected to eachswing rod 51 and the driving mechanism 6. As a result, one force applied by the driving mechanism 6 is transformed into a plurality of forces through the connectingrod swing mechanism 5 so that theflap 1 is more balanced when a force is applied to theflap 1. In addition, eachswing rod 51 is driven to be synchronously rotated by means of the synchronous connectingrod 52, which is beneficial to balanced stress of theflap 1 so that theflap 1 slides stably on the guide rail mechanism 4. It should be understood for the person skilled in the art that a plurality ofswing rods 51 in this embodiment can also be designed according to an actual situation, so as to realize transformation from one force to a plurality of forces, which is beneficial to balanced stress of the flap. This is not elaborated herein. - Further, as a preference, as shown in
FIG. 11 , theswing rod 51 in this embodiment mainly consists of andrive swing rod 511 rotationally connected to the synchronous connectingrod 52 and a drivenswing rod 512 connected to thedrive swing rod 511. One end of the drivenswing rod 512 is rotationally connected to theframe 3 through theswing rod shaft 53, and the other end thereof is rotationally connected to theflap 1 through the rotatingshaft 54. Thedrive swing rod 511 is rotationally connected to the synchronous connectingrod 52 through asynchronous shaft 55. Therefore, a magnitude and a direction of the transmission force can be changed through mutual interaction and length change between thedrive swing rod 511 and the drivenswing rod 512, so that a moving path of theflap 1 meets actual requirements when a swing amplitude of the synchronous connectingrod 52 is relatively small. This is conducive to reducing a length of the synchronous connectingrod 52 and power of a drivingmotor 61, which is beneficial to a space layout inside a turnstile. - Further, as preference, as shown in
FIGS. 11 and 12 , in this embodiment, eachsynchronous shaft 55 is parallel to theswing rod shaft 53 and the rotating shaft. Thedrive swing rods 511 are parallel to each other; and the drivenswing rods 512 are parallel to each other. Through this arrangement, rotation of the drivenswing rod 512 and theactive swing rod 511 can be kept synchronized during a swing process of the synchronous connectingrod 52, so as to avoid a phenomenon of inclination caused by upper and lower uneven forces on theflap 1 during a movement process of theflap 1. - Further, as a preference, in this embodiment, an axial direction of the synchronous connecting
rod 52 and a sliding direction of theflap 1 on the guide rail mechanism 4 are perpendicular to each other. Shaft centers between theswing rod shafts 53 and shaft centers between the rotating shafts are all located on the same axis parallel to the synchronous connectingrod 52. Therefore, the connectingrod swing mechanism 5 forms a stable parallelogram structure, which is beneficial to design and control of strokes of the synchronous connectingrod 52 and theflap 1. - Further, as preference, the
drive swing rod 511 and the drivenswing rod 512 are perpendicular to each other in this embodiment, so as to improve a rigid connection between thedrive swing rod 511 and the drivenswing rod 512 and optimize transmission efficiency. - Referring to
FIG. 4 in the forgoing embodiment, the base in this embodiment is provided with a swingrod shaft hole 19 for inserting one end of thecorresponding swing shaft 53 and forming a rotatable connection through a correspondingbearing sleeve 531. One end of theswing shaft 53 is also inserted into a through hole (marked in the drawings) of the drivenswing rod 512 to form a rotatable connection through the correspondingbearing sleeve 531. In the same way, two ends of the rotating shaft adopt the corresponding bearing sleeve to form a rotatable connection with theflap 1 and the drivenswing rod 512, respectively. Here, it should be noted that theswing rod shaft 53 and the rotating shaft in this embodiment can be rotationally connected through a pivot connection and the like, in addition to through the bearing sleeve. In the same way, thesynchronous shaft 55 can also interact with the corresponding bearing sleeve to realize a rotatable connection between thedrive swing rod 512 and the synchronous connectingrod 52, and a rotatable connection between the revolvingarm 63 and the synchronous connectingrod 52. This embodiment does not specifically limit and describe this herein. - In addition, it should be noted that a length of the
drive swing rod 511 in this embodiment is less than a length of the drivenswing rod 512, and a position where thedrive swing rod 511 is rotationally connected to the synchronous connectingrod 52 through thesynchronous shaft 55 is lower than a position where thedrive swing rod 51 is rotationally connected to and hinged with theframe 3, which is beneficial to a layout of the connectingrod swing mechanism 5 inside the turnstile. - In addition, referring to
FIGS. 4 to 6 of the forgoing embodiment, it can be seen that theflap 1 in this embodiment can consist of aflap body 11, abracket 12, a sliding rail arranged on thebracket 12, and theslider 14 slidably arranged on the sliding rail for being rotationally connected to the connectingrod swing mechanism 5. Through relative movement between theslider 14 and theflap body 11, theflap body 11 restricts upward degree of freedom of the flap body under its own weight, and restricts downward degree of freedom of the flap body under support of the guide rail mechanism 4. Therefore, when the connectingrod swing mechanism 5 swings, a translational thrust is generated on theflap 1, and a phenomenon of jamming at one end of a rotatable connection between the connectingrod swing mechanism 5 and theflap 1 is avoided when theflap 1 slides on the guide rail mechanism 4. - As a preference, referring to
FIG. 5 of the forgoing embodiment, the sliding rail in this embodiment is a linear sliding rail, and a sliding direction of theslider 14 is perpendicular to a sliding direction of theflap 1 on the guide rail mechanism 4. Therefore, when theslider 14 is driven by the connectingrod swing mechanism 5 to swing leftwards and rightwards, a relative linear movement is generated between the linear sliding rail and theslider 14, so that a thrust generated by the connectingrod swing mechanism 5 is transformed to be a translational thrust parallel to a sliding direction of theflap 1 to the maximum extent. - It should be noted that the sliding
rail 13 in this embodiment can also be designed in an arc shape or other regular or irregular shapes according to actual conditions. This embodiment only uses the slidingrail 13 as the linear sliding rail for brief description. - Referring to
FIG. 5 , there are preferably twosliders 14 in this embodiment, which are rotationally connected to the correspondingswing rod shaft 53 in the connectingrod swing mechanism 5, respectively. It should be understood that other number ofsliders 14 in this embodiment can also be selected according to actual needs, and no specific limitation and description are made herein. - In addition, the
flap 1 in this embodiment further includes an adjustingrod 15 parallel to an axial direction of the linear sliding rail and connected to thesliders 14 for adjusting a distance between thesliders 14 to ensure synchronism of thesliders 14 when thesliders 14 move to the maximum extent, and to avoid a phenomenon that theflap 1 is inclined due to uneven stress during movement while eliminating rotation movement of theflap 1 when theflap 1 moves. - In details, as shown in
FIG. 5 , theflap 1 further includes a sliderdistance adjusting cap 16 arranged on theslider 14 for adjusting a length of the adjustingrod 15 to facilitate the user's adjustment and assembly. As a preference, a length of the adjustingrod 15 in this embodiment is equal to a distance between theswing rod shafts 53 ofswing rods 51 that are connected correspondingly. In conjunction with the connectingrod swing mechanism 5, a parallelogram structure is formed to ensure that a sliding direction and a sliding distance of eachslider 14 are consistent. - In addition, it should be noted that the forgoing adjusting
rod 15 can be detachably connected to theslider 14, or can be connected as a whole according to actual needs. In addition, there is one adjustingrod 15 in this embodiment. In actual application, the number of adjustingrods 15 can be set to corresponding two, three, and so on according to the actual number of thesliders 14. Therefore, this embodiment does not specifically limit and elaborate this. - In addition, more preferably, the forgoing
slider 14 is preferably a self-lubricating silent slider, so as to eliminate noise generated when theslider 14 and the slidingrail 13 move as much as possible. Theflap body 11 adopts a tempered glass flap, and thebracket 12 consists of a flappanel fixing frame 121 and a slidingrail fixing seat 122 arranged on the flappanel fixing frame 121. - Referring to
FIGS. 5 and 6 , theslider 14 in this embodiment consists of aslider body 141 slidably arranged on the slidingrail 13 and aslider fixing seat 142 arranged on theslider body 141 to facilitate installation of therotating shaft 54. - As shown in
FIG. 10 , the forgoing driving mechanism 6 further includes the revolvingarm 63 rotationally connected to the connectingrod swing mechanism 5 at one end thereof, arotating arm 64 rotationally connected to the revolvingarm 63 through a connectingshaft 65, and a drivingshaft 62 of the driving motor 61 a rotationally connected to therotating arm 64. Therotating arm 64 is driven by the drivingshaft 62 to perform a circular motion. With this structure, a rotation motion of the drivingmotor 61 is transformed into a circular motion of therotating arm 64, and therotating arm 63 is enabled to swing regularly so that theflap 1 is regularly translated under the influence of the interaction with the guide rail mechanism 4, which improves control accuracy. - It should be noted that in this embodiment, as a preference, the
swing arm 63 and the synchronous connectingrod 52 in this embodiment are hinged by aconnection shaft 66. Obviously, the revolvingarm 63 in this embodiment can also be directly hinged with theswing rod 51 according to actual needs, without using the synchronous connectingrod 52. Therefore, whether theswing arm 63 is hinged with the synchronous connectingrod 52 or directly connected to theswing rod 51 is not limited and elaborated in details in this embodiment. - In order to briefly explain a working principle of the switch device of this embodiment, the switch device of this embodiment consists of two symmetrically arranged
flaps 1, thebase 2, theframe 3, the guide rail mechanism 4 arranged on thebase 2 and movably connected to theflap 1, the connectingrod swing mechanism 5 arranged on theframe 3, and the driving mechanism 6, where the twobases 2 and theframe 3 are located in a housing of the turnstile, respectively, and the turnstile passage part is formed between the two housings. - As shown in
FIGS. 11 and 12 , the twoflaps 1 move towards each other and gradually move closer to each other while moving from an open position to a closed position along theguide rail 41 under a swing action of the corresponding connectingrod swing mechanism 5, so that the turnstile passage is closed when reaching the closed position. As shown inFIG. 2 , when the twoflaps 1 move along theguide rail 41 from the closed position to the open position under the swing action of the corresponding connectingrod swing mechanism 5, the two flaps move backwards from each other and gradually separate from each other, thereby achieving opening of the turnstile passage. - In details, as shown in
FIG. 14 , the forgoing driving mechanism 6 further includes anopening limiter 8 and a closing limiter 9 that are arranged on theframe 3. Theflap 1 is in the open position when therotating arm 64 touches theopening limiter 8 and stops rotating. Theflap 1 is in the closed position when therotating arm 64 touches the closing limiter 9 and stops rotating. Therefore, through interaction of theopening limiter 8 and the closing limiter 9, a swing angle of the rotating arm is limited, thereby limiting a swing amplitude of aswing arm 63, then controlling a swing amplitude of the connecting rod swing mechanism, and further controlling a movement stroke and a movement range of theflap 1. - In addition, it is understandable that in this embodiment, in order to intelligently control a flap opening speed, a flap closing speed and strength of the
flap 1, the driving mechanism 6 further selectively includes a protective cover fixedly connected to theframe 3, an electromagnetic brake assembly arranged in the protective cover and connected to the drivingshaft 62, and a controller electrically connected to the electromagnetic brake assembly and the drivingmotor 61 according to actual needs. - The
electromagnetic brake 20 assembly in this embodiment can consist of anelectromagnetic brake 20, aprotective cover 10, and a brake shaft. Theelectromagnetic brake 20 is mounted in theprotective cover 10. One end of theprotective cover 10 is connected and fixed to the drivingmotor 61, and the other end thereof is connected and fixed to theframe 3. A stator of theelectromagnetic brake 20 is fixed in theprotective cover 10. The brake shaft is also arranged in theprotective cover 10. One end of the brake shaft is fixed on an output shaft of the drivingmotor 61, and the other end thereof is connected and fixed on a motor output connecting rod. A rotor of theelectromagnetic brake 20 is mounted on the brake shaft. A contact surface gap between the stator and the rotor is adjusted according to requirements of a manufacturer. In this case, after the stator of theelectromagnetic brake 20 is powered on, the rotor is attracted by the stator to have a certain adsorption force as a whole, and the rotor is forced to stop moving; therefore, the driving mechanism 6 is stopped, that is, theflap 1 is forced to stop moving. -
Embodiment 5 of the present invention provides a switch device of a turnstile passage. This embodiment is substantially the same as any one of the forgoingEmbodiment 3 to Embodiment 4, and difference therebetween lies in: - In this embodiment, when an
opening limiter 8 rotates to an angle corresponding to aflap 1 at an open position, a distance of 1 to 5 mm is retained between theopening limiter 8 and a revolvingarm 63. Similarly, when a closing limiter 9 in this embodiment rotates to an angle corresponding to theflap 1 at a closed position, a distance of 1 to 5 mm is retained between the closing limiter 9 and the revolvingarm 63. Therefore, with this structure and program design of a controller, it is possible to prevent a phenomenon that theopening limiter 8 and the closing limiter 9 are damaged by frequent collisions. - In addition, it should be noted that the closing limiter 9 and the
opening limiter 8 in this embodiment can be arranged as stop blocks or limit switches according to actual needs, and no specific limitation and description are made here. - In addition, in an alternative embodiment of the present application, a
resetting mechanism 7 can also be replaced by a structure that realizes the same resetting function, such as rebound of a compression spring, in addition to atension spring 73, which is not elaborated here. - The forgoing embodiments are only used to illustrate the technical solutions of the present invention without limiting the same in any way, and the present invention is only described in detail with reference to the preferred embodiments. The person skilled in the art should understand that modifications or equivalent replacements can be made to the technical solutions of the present invention without departing from the scope of the technical solutions of the present invention. All these modifications or equivalent replacements shall fall within the scope of the claims of the present invention.
